Dr. Shelley Smith’s research involves the localization and identification of genes that contribute to communication disorders in children, particularly reading disability (dyslexia), language impairment, speech sound (phonologic) disorder, and attention deficit hyperactivity disorder. These conditions can be distinct clinically, but have some overlap in their underlying developmental mechanisms. Identification of the genetic and environmental interactions that affect language and learning abilities can lead to the discovery of the neurodevelopmental processes that are impeded by these disorders. This should aid in the development of improved diagnostic and treatment procedures based on the etiologic factors at the heart of each child’s difficulties. These studies are done in collaboration with the University of Colorado, the University of Denver, and the University of Kansas.
